According to the piece published Thursday, contributor Evan Gahr followed up on the slavery comment by asking Carson why he thought President Obama's health care law was worse than 9/11. Carson responded that the terror attacks were an "isolated incident."

Gahr continued to pepper the retired neurosurgeon with follow-up questions and wrote that he was frequented interrupted by Carson's business manager. Here's their exchange:

Me: “Who do you think caused families more pain—Obamacare or Osama bin Laden?”

Carson: “Let me explain.”

Williams: “Let him answer the question!”

Carson: “Things that are isolated issues as opposed to things that fundamentally change the United Sates of America and shift power from the people to the government. That is a huge shift.”

Me: “Right. But what do you think caused specific families more pain—Obamacare or Osama?”

Carson: “You have to take a long term.”

Me: “You’re not answering the question.”

Carson: "Will you listen? You have to take a long-term look at something that fundamentally changes the power structure of America. You have to be someone who reads. Who is well-read. I want you to go back tonight and pull out what Saul Alinsky says about health care under the control of the government."

Gahr's interview with Carson was cut off after the dustup, he wrote.

Carson also criticized Obamacare recently in the context of the Veterans Affairs scandal, using the VA's long hospital backlogs to slam the health care law.

"I think what’s happening with the veterans is a gift from God to show us what happens when you take layers and layers of bureaucracy and place them between the patients and the health care provider," Carson said on Fox News. “And if we can’t get it right, with the relatively small number of veterans, how in the world are you going to do it with the entire population?”
